Hi Lazio, i installed the latest version of unity on my laptop this time (windows 10)and everything seems fine.. i still wonder about my desktop tho? anyway i had a lot of software installed on that desktop it was probably a conflict of some sort, i'm sure if i did a fresh reinstall of windows 10 on the desktop everything would be fine. You can mark this resolved, so far from playing with bolt i was easily able to transform a cube and so on - it's fast and logical in a graphic way. Thanks for the great software.
